Specification of Letters Patent...

Patented Dec. 25, 1906;

Application filed November 24, 1905.. Serial No. 288,848.

To all whom it may concern.-

Be it known that I, J ANG LANDSING, a citizen of the United States, and a resident of Boonton, Morris county, Stateof New Jersey, have invented certain new. and useful Improvements in Storage- Battery- Plates, of which the following is a specification, accompanied by drawings.

This invention relates to improvements in storage-battery plates, more particularly to Plant plates, in which the active material is formed out of and .upon lead portions of the electrodes by chemical or electrochemical action.

The object of the present invention is to improve upon the construction of'such Plant plates and prevent the plate from buckling as the lead strips thicken and elongatein the process of formation.

Further objects of the invention will hereinafter appear; and to these ends the invention consists of a storage-battery plate for carrying out the above objects embodying the features of construction, combinations of elements, and arrangement of parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the accomwhich- Figure 1 is a side view of a portion of a plate embodying the invention. -Fig. 2 is a side view of a portion of a plate embodying a modification. Figs. 3 and 4 are side views of portions of modified plates, and Figs. 5 and 6 are side views, of portions of modified plates.

Referring to the drawings, A and B represent the sides or framework of the plate, which may be of lead or an alloy, as lead and antimony.

C represents a vertical cross'rib, and D is a horizontal cross-rib.

Within the space formed by the frame A B and cross-ribs 0 Dis a sh mentary grill of lead constructed in accordance with this invention in suchmanner as to prevent buckling. The complete plate may be made up of as many elementary panels or grills fo rming unit elements as de= sired, but one grill being shown by way of illustration. Y

As shown, the grill comprises the elementary units or strips E, adapted ,to become own a panel or eleactive, and these strips or units are connected by flexible cross members or supports F. As shown, short ends ments project beyond the upper and lower 1 cross-supports F, and spaces H are provided between said ends and the frame and ribs to permit elongation of the grill longitudinally or in the direction of the extent of the unit strips E. Spaces I are formed at each side of the grill substantially .opposite the ends of the cross members or supports F to permit sidewise elongation of said members. Accordin to the construction shown and describe in Fig. 1 provision is .afl'ordedfor both elongation and thickening of the unit strips E and of the cross members or supports F.

In Fig. 2- a construction substantially like Fig. 1 is shown, with the ad 'tion of a central space J in the grill, so that the grill may expand inward from either side to fill the space, thus preventing the outer portions of the grill from pressing outward and bulgin against the outside frame of mi ht also be distorted by such action,

fn Fig. 3 continuous side vided at each. side of the grill to ermit transverse expansion of the grill, and the extreme I cross members or supports F are connected to the frame and cross-ribs flexible bent straps L, which to expand both. longitudin versely, or, in other words, .in

In Fig. 4 a modification of Fig. 3 is shown, in which the spaces K are provided at each side of the grill; but the connecting-strips-L extend from the grill to the frame and ribs toby means of vpermit the grill a ly and transall directions.

other, while additional spaces O are provided between said strips L and the frame and cross-ribs, so that additional rovision for expansion is made and the gril may expand in all directions into the recesses HfO, and K.

In Fig. 5 a modification is shown in which the grill is connected at the corners by diagonal strips P, extending across the corners and leaving spaces Q in the corners. The spaces H are provided, as before, at the'ends of the grill, andthe spaces K are provided at the sides. According to this construction the grill may expand ner-spaces receive the expansion from twcdi- I rectlons.

the plate, which ward each other instead of away from each i in all directions and tl1e.cor-.

spaces K are probroken, anduspac'es are left' between the" 'broken; ends, into r In Fig.- 6 the cross supports or members which connect the unit strips are crooked or which they may expand Within the grill. I The broken pieces of-the cross supports or members are represented by R, and the'spaces to permit expansion are represented b S. As before, spaces H are rovided at the ends of the grill to provide or expansion.

The plate may be formed in any desired manner, one satisfactory method being to cast theindividual rills in any desired manner and then assem le as many as necessary for the plate and cast the frame around them.

I claim, and desire to obtain by Letters Pat ent, 'the'followin'g:

= 1. A Plant battery-plate having a frame rovi'ded with ribs, active members in the torm of unit strips supported at a plurality of -points by cr'oss-supports-seizured to the ribs,

2. A Plant battery-plate having a frame provided with ribs, active members in the o' f'orm' ofunit strips supported at a plurality of points by cross-supports secured to the ribs, said plate havin intervals opposite the ends of the strips to ai iord provision for r the outer cross-supports bein oonnectedby flexible strips to the oornersoI the frame and i to the ribs, the platealso having spaces oppoi site the ends of the cross-supports to' permit expansion.
